1 Samuel 7:6

2From the day that the ark stayed in Kiriath Jearim, the time was long—for it was twenty years; and all the house of Israel lamented after the LORD.

3Samuel spoke to all the house of Israel, saying, “If you are returning to the LORD with all your heart, then put away the foreign gods and the Ashtaroth from among you, and direct your hearts to the LORD, and serve him only; and he will deliver you out of the hand of the Philistines.”

4Then the children of Israel removed the Baals and the Ashtaroth, and served the LORD only.

5Samuel said, “Gather all Israel to Mizpah, and I will pray to the LORD for you.”

6They gathered together to Mizpah, and drew water, and poured it out before the LORD, and fasted on that day, and said there, “We have sinned against the LORD.” Samuel judged the children of Israel in Mizpah.

7When the Philistines heard that the children of Israel were gathered together at Mizpah, the lords of the Philistines went up against Israel. When the children of Israel heard it, they were afraid of the Philistines.

8The children of Israel said to Samuel, “Don’t stop crying to the LORD our God for us, that he will save us out of the hand of the Philistines.”

9Samuel took a suckling lamb, and offered it for a whole burnt offering to the LORD. Samuel cried to the LORD for Israel, and the LORD answered him.

10As Samuel was offering up the burnt offering, the Philistines came near to battle against Israel; but the LORD thundered with a great thunder on that day on the Philistines and confused them; and they were struck down before Israel.
